Sure thing. If you cut the power in half, the NOx will be reduced in [almost] half. I meant that Urea injection will allow for reduced NOx without sacrificing the power and efficiency too much. Reports mention that X5 diesel passed the [real world] tests with flying colors. I dont know which model it was, but E70 is down only 20 or so hp (5-6%)of the ROW model. Thanks to the Urea injection.
